Electrons are emitted from the surface of a metal when it's exposed to light. This is called the photoelectric effect. Each metal has a certain threshold frequency of light, below which nothing happens. Right at this threshold frequency, an electron is emitted. Above this frequency, the electron is emitted and the extra energy is transferred to the electron. The equation for this phenomenon is KE=hν−hν0KE=hν−hν0 where KEKEKE is the kinetic energy of the emitted electron, h=6.63×10−34J⋅sh=6.63×10−34J⋅s is Planck's constant, ννnu...
